Thermal-Noise Imaging Captures Tiny Biological Tissues

Imagine standing in a dark room in which a single, glowing ball is bouncing around. The ball avoids a region in the center of the room. Over time, you might conclude that an object sits in that region, even though you cannot see it. That thought experiment illustrates thermal-noise imaging, a technique that a team at a U.S. university has applied to nanoscale imaging of soft biological structures (Nat. Commun., doi: 10.1038/ncomms12729). The technique could lead to new means for studying live cells and other tiny biological structures.”
